Laser marking anodized aluminum is a selective process known as laser etching.

Laser etching on anodized aluminum.

Anodised aluminium can be engraved efficiently and precisely with a laser machine. Black laser marking on anodized aluminum. Barcodes data matrix codes dmc alphanumeric numbers can be engraved directly on the surface. Depending on the color of the anodized aluminum itself a fiber marking laser can efficiently produce darker marks while a co2 marking system can produce bright engraving with contrast.

This instructable will show you how to use a laser cutter to etch anodized aluminum. To laser mark aluminum you should use a fiber laser system. Laser etching anodized aluminum. There are two types of lasers used for etching or scribing laser engraving metal surfaces.

A white marking is produced when the anodised layer is removed. Another important point when engraving anodized aluminium is that the engraving must be done fast. While this method is perfectly suited for coloured anodised coatings for natural anodised. The laser beam only removes the anodized layer from the aluminum piece resulting in high quality marks.

In this case the ls 1630 produced excellent r. This type of laser is capable of scribing right through the anodic coating to the bare substrate underneath. This will give the most contrast when engraved. Laser marking engraving or etching of anodized aluminum is perfect to do direct part marking.

When engraving onto anodized aluminum it is important that the vector graphic is produced using a rgb colour palette and that the engraving colour is black rgb value 0 0 0. The color of the mark is highly contrasted between the anodized aluminum and the laser induced mark. Laser machines are an ideal technology for marking and engraving on anodized aluminum and can be used with both co2 and fiber systems. Yag for yttrium aluminum garnet is a crystalline solid state laser that emits a wavelength of 1 064 micrometers 1064 nanometers.
